6mmBR - 103 Vapor Trail

[Bill Norris]

Anybody care to share load data for this bullet ?

 

[SG4247]

Factory Savage F-class 6BR with a Bartlien 4 groove barrel. First powder charge test Using Varget with 103s. A light breeze caught me on one shot in group 2.

Not a Vapor Trail but a 103 custom bullet in 6br, 29.3gns Varget, 8jam gives me 2880-2890fps in 30” 8tw Kreiger..

Are we speaking of the hand pulled Vapor Trail or the automated VTac

I have no clue I purchased them from a member here on the site.

These are automated 103 over RL-15, I suspect Varget may tighten things up a tad though
I haven’t got around to testing yet to provide data.

The member I purchased them from just told me in a P M they are the hand-pulled model.

I can tell anyone reading this that Rushty's info is "Spot On" for the Copper Head 103's that we can get from a custom maker here in the Land of OZ...
Took out a 300 meter {328 yds} range record with 10 shots in a 1.75" group... Green dot is a a sighter/ranging shot and not in the group.
If #8 had been inside or on top of #6 the group would have been 1.5"
The primers were CCI-450's and my barrel is a Bench Mark 28" 1:8 mounted on a Pierce tube action in a Competition Machine R-5 stock by Garry Eliseo.

Look between 29.5 & 30.8g of Varget. Working up slowly, looking for pressure. I start with them about .02” longer than touch & work backwards from there after narrowing the charge window.

Fantastic Bullets. Find a load and then you can load up on the VT-Tacs for cheap. From my experience, they’ll shoot the same load well.

^^^^^
I was just thinking about that last night.
I have a small supply of both Bullets I’m working with that measure very close to one another.

I just loaded VT-Tacs for an informal shoot with some buddies tomorrow after some testing with the hand pulled. After finding my length at touch, then loading the two bullets the same length relative to the lands, I ended up moving my Wilson seater .002”.

 

[JFrank]

So .002 different at the seating stem, that’s definitely good to know.
My OAL is near identical however the BBTO is slightly different. ( using my crappy tools )

If you paid .35 each they are automated, if they were over .50 they are hand pulled.

30.2 vv n140. Touching the lands. Shoots very well.
